François Henri de Montmorency-Bouteville Luxembourg, duc de

Luxembourg, François Henri de Montmorency-Bouteville, duc de (fräNswäˈ äNrēˈ də môNmôräNsēˈbōtvēlˈ dük də lüksäNbōrˈ) [key], 1628–95, marshal of France. Under his cousin, the Great Condé, he served in the Fronde, in the conquest of Franche-Comté (1668), and in the Dutch War. Made a marshal in 1675, he was given (1676) command on the Rhine and shared in the victory of Cassel (1677). He was implicated in the Poison Affair and was sent to the Bastille (1679–80). Although still out of favor at the beginning of the War of the Grand Alliance, he was eventually given command in Flanders and won three battles on which his reputation chiefly rests—Fleurus (1690), Steenkerke (1692), and Neerwinden (1693).
